other leds?
« on: March 09, 2008, 11:18:57 AM »
hi guys, just wondering what is the second smallest leds after 0603 leds as i find them to hard to solder to, and if i buy a different kind of led, will a 10ohm resistor be ok for it?
thankyou

get 0805, they are bigger and VERY easy to solder and you can still use them perfectly (i even used them for the led swap mod)

the battery has too high voltage for them! You have to chceck the maximum voltage you can apply to your leds otherwise they will immediately burn out

dude the battery has got to much voltage and also packs 1AMP thro them!!!, i mean leds are only surposed to run with 20mah let alone 1AMP!!! of course they are gona burn themself's silly unless you add a resistor :taunt:

One day I was just playing with a couple different LEDs I had.  I don't remember what I connected one of them to but it glowed orange, different than it's normal color, and made a kind of whining sound before it exploded..... Good thing I had safety glasses on, a small piece hit them and melted on.  :boxed:
